This application is a division of my copending application, Ser. No. 651,021, filed July 12, 1923.

This invent-ion relates to a novel and improved arrangement of boiler doors and will be best understood from the following description and the accompanying drawings, in which I have shown a selected embodiment of my invention and in which Fig. 1 is a front view of a portion of a. boiler, showing a plurality of doors arranged according to my invention.

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a view showing how a platform may be temporarily supported on a door.

Fig. 4 is a section taken on the line t1 of Fig. 5.

Fig. 5 is a view taken on the lines 5-5 of Figs. 4 and 6.

Fig. 6 is a section on the line 66 of F ig. 5.

Fig. 7 is a section on the line 77 of Fi Ileferring now to the drawings in detail, I have shown the invention as used in connection with a boiler, a part of which is shown in Fig. 2, which comprises vertical water chambers 1 and 2, which are connected to banks of tubes 3 and 4. The tubes are shown as being horizontally inclined and the space in front of the water chambers is closed by a pluralityof doors 5. lVhen it is necessary to clean or remove tubes, or make any other repairs to the boiler, it is desirable to re move one or more doors and to facilitate this removal and the subsequent replacement, I have devised the arrangement forming the subject matter of this application.

Extending transversely of the boiler and in front of the water chambers, is a lintel 6, upon which each door is hung by means of a plurality of hooks 7. Disposed in front of the lintel 6 is a track here shown as an Lbeam 8, upon which runs a hoist 9 having a hook 10 which is adapted to engage an attaching member 11 upon each door. Each door is secured in position by suitable clamps 12 which are mounted upon vertical side pieces 13, and which may be manually operated. It will be noted that each hook 7 is so arranged with respect to the lintel 6 which it engages thatza limited amount ofhorizontal movement of the door with respect to the lintel is permitted.

In'Figs'. '1 and- 2, I haveshownwone door 5 as in the condition of being removed or replaced and it will be seen :thatxa lifting of the door by the hoist after the clamps have been unfastened, .will remove the" door and cause it "to swing outwardlyaway from the boiler. On the other hand, if it is desired, the hooks :7 may be left in "engagement with the lintel and the 'door may "be swung'outwardly to .the full line position shown in Fig. 3. The normal position of the door is shownin dot and. dash lines .inthis figure. I'Vhen'the door has been thus swung out- *war'dly, a suitableplatform 14 may be placed between the door andsthe boiler, resting upon the'angle iron 15at the bottom of the door and upon the horizontal sill 16. The platform is then "in position to be occupied by workmen-engaged in repairs or other work -on the boiler.

The angle iron '15-preferably extends completely across the. bottom of the door and finds its counterparts in other angle irons 15 disposedadjacent other edges of the door. Between the lintel 6 and the upper edge of the'door, isdisposed-a suitable packing mao iterial 17 which is compressed and thus seals 'the joint between the lintel and the door, whenthe door is in position. Similar pack- :ing material is disposed between each edge .of the door and adjacent supporting memrbQIS such asthe vertical members 13 and the horizontalemember 16. l 'By'the arrangement shown, not only are the doors made tight against the frame of the opening so as to prevent the passage of :gas from the boiler to the exterior or the Elealrage of air into'the boiler, but the space between the waterychazmbers and the casing --is :also closed so asto prevent. the short 'circuiting of :gases through this space, itbeing noted? thatth-elintel, sill, and vertical rmembers. are-all-sealed to the boiler.

It will be obvious that the doors .may be i clined somewhat to the verticalwithout departing from'my inventionand in therappended claims, when I have described the doors as substantially vertical, it will be understood that the term includes any arrangement in which the doors are either strictly vertical or inclined to the vertical.

It will be understood that the arrangement described is merely illustrative and that the application of my embodiment may be widely Varied.

I claim:

1. In a boiler casing, a substantially vertical door adapted to cover an opening in the casing, a lintel above the opening, hooks on the top of the door to engage the lintel to support the door and having limited horizontal movement thereon away from the easing, and clamps around the edges of the door to hold the same in contact with the frame of the opening.

2. In a boiler casing, a substantially vertical door adapted to cover an opening in the casing, a lintel above the opening, hooks on the top of the door to engage the lintel to support the door and having limited horizontal movement thereon away from the easing, packing between the edges of the door and the frame of the opening and clamps around the edges of the door to hold and compress the packing between the door and the frame.

3. In a boiler casing, a substantially vertical door adapted to cover an opening in the casing, a lintel above the opening, hooks on the top of the door to engage the lintel to to the frame.

WILLIAM A. JONES.

support the door and having limited horizontal movement thereon away from the casing, and clamps around the edges of the door to hold the same in contact with the frame of the opening, the face of the door being substantially vertical when the door is supported on the hooks alone.

4. In a casing for a water tube boiler having horizontally inclined tubes and water chambers at either end thereof,-a lintel and a sill parallel thereto, verticalside pieces extending from the sill to the lintel to form therewith the frame of an opening with the outer edge of the frame spaced outwardly I from the water chamber, the lintel and the sill being sealed to the water chamber, and

doors over said opening and sealed to the frame thereof, whereby a sealed space is formed between'the water chamberv and the doors.

, 5. In a boiler casing, a substantially vertical door adapted to cover an opening-in the casing, a lintel above the opening, pivotal connections between the top of the door and the lintel to support the door, said connections being arranged to permit the bottom of the door to be swung away from the sill and the door and the sill being arranged to support a platform inserted between the bottom of the door and the sill to hold the door infits outer position. i a
